Mate, okay I'm not a big electric-user, but I spent £350 on a 65w solar panel, and that provides for all my needs at the moment. . . (basically, to be fair, only laptop, mobile, amp, and lighting) . . . In the winter, I have to use the petrol-gennie to make up the slack, maybe two litres a week . . .

I believe this. The cost per KWH of solar power has been coming down a lot lately and at the same time the price of oil has been going up. It can't take too much longer before the two lines cross. Green energy is definitely the wave of the future, with peak oil driving up oil prices and all the trouble with nuclear power recently, i.e. the Japanese meltdown. It's definitely something who's time has come, and I for one say it's about damned time.
